Hybrid Transmission
In hybrid transmission mode, the UMTS E1/T1 port and LTE FE/GE port serve as shared ports
to connect to the transmission equipment. The E1/T1 port is used to transmit the services with
high QoS requirements, such as CS services; and the FE/GE port is used to transmit the services
with low QoS requirements, such as PS services.
The UMTS E1/T1 port and the LTE FE/GE port are used for data transmission in a UMTS+LTE
base station in hybrid transmission mode. When the UMTS FE/GE port and the LTE FE/GE
port are used for data transmission, hybrid transmission is not applicable.
